BRAKE-1VIAST.

Specification of Letters Patent.

Patented Nov. 9,1915.

Application filed April 24. 1914. Serial No. 834,128.

To all whom it may concern Be it known that 1, JOHN P. ANDERSON, citizen of the United States, residing at No. 701 North Rebecca street, Pittsburgh, in the county of Allegheny and State of Pennsylrection, the top portions of such mast extending above the top edges of the walls of the car. While loading these cars with coal, billets or other heavy material, the portions of the brake masts extending above the walls of the cars are often bent so badly by contact with the loading machinery or material that the mast as a whole is rendered inoperative. An object of the invention is to provide a brake mast, which when applied to a car may be lowered from its normal operable position, to a position where it will still be operable and also less liable to damage when the car is being loaded or unloaded.

Another object of the invention is to provide novel means for holding a brake mast to a car in its preferred operable position.

These and other objects will appear in the following specification and in the appended claims. v V I Referring now to the drawings in which like reference characters refer to like parts, and in which 7 Figure l is a plan view of a portion of a car embodying the invention; Fig. 2 is an end elevational view of the same; Fig. 3 is an enlarged detail plan view of the operated portion of the brake mast; Fig. a: is a vertical sectional view of the same taken on the line 4 4: of Fig. 3; Fig. 5 is an enlarged detail view of the operating portion of the brake mast; Figs. 6 and 7 are detail plan and side views respectively of the combined bearing and clamp member, the parts being shown separated, and Fig.8 is an enlarged view of a locking and safety chain.

Referring now in detail to the drawings, 1 indicates the end wall'of a car, and 2 a brake step which is attached to the brackets 3, 3 that are secured to the end wall.

4 indicates a brake mast which comprises an operated or chain winding part 5 and an operating part 6. The part 5 is made preferably of cast metal and is provided with an opening 7 that preferably extends the full length thereof. This opening 7 at its upper end 1s preferably square and is adapted to rece ve a portion of the operating part 6 hereinafter more fully described. The bottom portion of this part 5 is seated on and supported by a bracket 8 which may be secured to any suitable member of the car. To keep the part 5 in its operative position, the contracted portion 9 is passed through a perforation in the bracket 8.

10 indicates the chain winding portion of the part 5. The upper portion of the part 5 1s Journaled in a member 11 which is preferabl-y secured to the brake step 2. Above the brake step 2 this upper portion of the part 5 is provided with a ratchet wheel" 12, with which a pawl 13, pivotally mounted on the step 2, is adapted to engage. The ratchet wheel 12 preferably integral with the part 5, but if desired it may be made separate and connected thereto by a key or other suitable means.

The operating part 6 of the brake mast is provided at one end with the ordinary hand wheel 1%, and at the other end is provided w th a portion 15 which is preferably square 1n form and is adapted to fit loosely in the square portion of the opening 7 in the part 5. Intermediate the hand wheell l and the portion 15, the operating part 6 is provided with a collar 16 which may be secured thereto by any suitable means. It will be seen that this collar may be made integral with the part 6.

17 indicates the combined bracket and clamp member which preferably comprises a bracket part 18 and a clamp part 19. The bracket part 18 is preferably of angular form having a portion 20 which is adapted to be secured to the wall 1 of the car, and a portion 21 which extends outwardly from the portion 20. This portion 21 is provided with a bearing portion 22 and with petforated lugs 23 and 2 1. The clamp part 19 comprises an upper portion 25 and a lower portion 26, which portions are spaced apart. and connected together by a bearing portion 2-7, thus forming a recess or pocket 28. The ends 29 of the portions 25 and 26 of the part 19 fit loosely over the lug 23 of the part 18, and are adapted to be pivotally connected thereto by a pin 30 which pin may be held against loss by-the head 31 and the cotter 7 its closed position, are adapted to register with the perforation in the lug 2 1. To hold the part 19 in closed position, a member 3 1 is provided which is passed through the perforations in both of the parts 18 and 19.

To prevent-the loss of this member 34:, a

flexible member 35 is provided, one end of which is fastened to the member 34: and the other end of which is preferably fastened to the part 18; e 7

When the operating part '6 of the brake mast is inits preferred vertical position as shown in fulllines inFig. 2 of the drawings, the collar 16 on the part 6 isreceived within the recess or pocket 28 in the part 19 of the combined bracket and clamp member 17 and is held against vertical movement by the portions 25 and 26 of such member'17. When the parts 25 and 26 0f the member 17 are in engagementwith the collar 16 itwill be seen that the portion 27 of the part 19 and the portion 22' of the part 18 of such member 17, form a bearing for the collar 16,

which bearing is adapted to steady the part 6 of the brake mast.

When it is desired to lower the part 6 of the brake mast from its preferred vertical position, the member 34: is removed from the parts 18 and 19-of the member 17, and the part 19 is then swung outwardly on its pivot until the portion 26 of such member is out of engagement with the collar 16 on the part 6 of the brake mast, at which time said part 6 drops to its lower operable position, as shown in dotted lines in Fig. 2 of the drawings. 1 Y s It will be seen that changes may be made in the detail and arrangement of the parts without departing from the spirit and scope of the invention. r I

Having thus described the invention, what I'claim as new and desire to secure by Letters Patent is: I

1. The combination with a car, of a brake mast comprising a plurality of parts, one of said parts being movable relative to the other of said parts, and means on said car adapted to engage said movable part and hold it in its preferred vertical position, said means forming a bearing for said movable part.
